SAMCO (TSE:6387) Stock Price Sinks Even As Profitability Strengthens

SAMCO holders just watched a bruising few months. The share price is down roughly 48% over 90 days, yet the latest quarter delivered Basic EPS of ¥106.32 on revenue of ¥3,386m. That disconnect is where the real story sits.

It can be tempting to assume that a falling chart means a broken company. The earnings print shows the business closed Q4 with profit of ¥854m and a trailing net margin of 20.7%. For now, the stock trades as if investors fear the growth will stall, while the reported numbers indicate a different picture.

Is SAMCO now priced like a growth outlier, or has the selloff already overshot fair value? Compare the recent earnings surge with the current multiple in our valuation analysis for SAMCO.

SAMCO earnings tilt the story toward resilience

SAMCO’s recent report gives the optimistic narrative some real backing. Revenue of ¥3,386m and net income of ¥854m both move in the same upward direction as Basic EPS of ¥106.32 per share. Profitability looks firmer, with the trailing net margin at 20.7%, which suggests the specialist equipment model is holding its own. For a business tied to semiconductor capital spending, that combination of higher sales and fatter margins argues that customers are still writing cheques and that the niche positioning is translating into healthier economics.

Share price slide keeps the cautious view alive

The chart tells a very different story. The stock is down about 48% over 90 days, with declines of roughly 26% over 30 days and 9.6% over the past week. That kind of selling alongside improving earnings signals worry about the cycle, order visibility, or balance sheet resilience even if the latest figures do not directly flag a crack in operations. For you as an investor, the mismatch between SAMCO’s recent profitability and the heavy drawdown keeps the cyclical, higher risk framing firmly on the table.
